After a few ski trips in slightly painful hire boots, I decided to buy a pair that would fit properly. After trying quite a lot of pairs, I eventually found some that fitted well all over my foot, which fit with either one thick pair of socks, or two thin ones. I've generally gone for one thick pair. For most of my current trip, they've been amazing, making skiing easier, avoiding painful feet, and keeping my feet toasty.

However, today it was a lot colder, especially on the higher runs, and my toes got very cold (almost painfully). Without buying a second pair that'd be big enough for two thick pairs of socks just for the odd very very cold day, is there anything that can be done to avoid cold feet on very cold days skiing?

Pocket hand/toe warmers contain different chemicals/powders that can create heat when activated. Try placing these inside and the back of your thigh along your arteries to warm the blood heading to your toes.

First and foremost: make sure you get your boots fitted properly by a professional boot fitter. A proper snug fit will allow blood flow around the foot keeping them warm.

Often cold feet are a sign of problems elsewhere. Once your body/core cools it pulls blood/heat in from the extremities. So layer up and it might just solve the problem.

Another often over looked factor is food intake. Keep an eye on your food and water intake. Make sure you eat smaller meals throughout the day. A big hearty alpine lunch can take a lot of blood and energy to digest. Leaving the poor ole toes without any.

Avoid too much Alcohol. The more you have the thinner the blood gets, the less effective it is at warming and powering the skiing machine that you are.

Stay hydrated. The body needs water to perform. Especially at altitude.

Yes, add fat to your feet. I don't mean gain weight. Just slather it on before putting socks on. Petroleum jelly will work, as will almost any other fat (other than coconut oil). A nice layer of fat, even external, does wonders for heat retention.

Never thought of this- the only times my feet get too cold are when my boots are too tight, or if they get wet (which is always a danger in Scottish snow)

@theJollySin -- Sadly I have tried it, only not with my feet. I can attest that it does work with larger areas of the body. I see no reason it wouldn't work for feet as well.

Seems like the negatives (gooey feet, gunked up and compressed liners/insulation) would make this temporary solution bad news for long-term comfort...
